Initializing the ValidMind Library

After creating an account with ValidMind, we can find the project’s API key and secret in the settings page of the ValidMind dashboard.

The library credentials can be configured in two ways:

  • By setting the VM_API_KEY and VM_API_SECRET environment variables or
  • By passing api_key and api_secret arguments to the init function like this:
vm.init(
    api_key='<your-api-key>',
    api_secret='<your-api-secret>',
    project="cl2r3k1ri000009jweny7ba1g"
)

The project argument is mandatory since it allows the library to associate all data collected with a specific account project.

import validmind as vm

vm.init(
  api_host = "http://localhost:3000/api/v1/tracking",
  project = "clhhz04x40000wcy6shay2oco"
)
Connected to ValidMind. Project: Customer Churn Model - Initial Validation (clhhz04x40000wcy6shay2oco)

Using a demo dataset

For this simple demonstration, we will use the following bank customer churn dataset from Kaggle: https://www.kaggle.com/code/kmalit/bank-customer-churn-prediction/data.

We will train a sample model and demonstrate the following library functionalities:

  • Logging information about a dataset
  • Running data quality tests on a dataset
  • Logging information about a model
  • Logging training metrics for a model
  • Running model evaluation tests

Running a data quality test plan

We will now run the default data quality test plan that will collect the following metadata from a dataset:

  • Field types and descriptions
  • Descriptive statistics
  • Data distribution histograms
  • Feature correlations

and will run a collection of data quality tests such as:

  • Class imbalance
  • Duplicates
  • High cardinality
  • Missing values
  • Skewness

ValidMind evaluates if the data quality metrics are within expected ranges. These thresholds or ranges can be further configured by model validators.

Load our demo dataset

Before running the test plan, we must first load the dataset into a Pandas DataFrame and initialize a ValidMind dataset object:

df = pd.read_csv("./datasets/bank_customer_churn.csv")

vm_dataset = vm.init_dataset(
    dataset=df,
    target_column="Exited",
    class_labels={
        "0": "Did not exit",
        "1": "Exited",
    }
)
Pandas dataset detected. Initializing VM Dataset instance...
Inferring dataset types...

Initialize and run the TabularDataset test plan

We can now initialize the TabularDataset test plan. The primary method of doing this is with the run_test_plan function from the vm module. This function takes in a test plan name (in this case tabular_dataset) and a dataset keyword argument (the vm_dataset object we created earlier):

vm.run_test_plan("tabular_dataset", dataset=vm_dataset)
tabular_plan = vm.run_test_plan("tabular_dataset", dataset=vm_dataset)

Metric rolling_stats_plot RollingStatsPlot This class provides a metric to visualize the stationarity of a given time series dataset by plotting the rolling mean and rolling standard deviation. The rolling mean represents the average of the time series data over a fixed-size sliding window, which helps in identifying trends in the data. The rolling standard deviation measures the variability of the data within the sliding window, showing any changes in volatility over time. By analyzing these plots, users can gain insights into the stationarity of the time series data and determine if any transformations or differencing operations are required before applying time series models.

Preparing the dataset for training

Before we train a model, we need to run some common minimal feature selection and engineering steps on the dataset:

  • Dropping irrelevant variables
  • Encoding categorical variables

Dropping irrelevant variables

The following variables will be dropped from the dataset:

  • RowNumber: it’s a unique identifier to the record
  • CustomerId: it’s a unique identifier to the customer
  • Surname: no predictive power for this variable
  • CreditScore: we didn’t observer any correlation between CreditScore and our target column Exited
df.drop(["RowNumber", "CustomerId", "Surname", "CreditScore"], axis=1, inplace=True)

Encoding categorical variables

We will apply one-hot or dummy encoding to the following variables:

  • Geography: only 3 unique values found in the dataset
  • Gender: convert from string to integer
genders = {"Male": 0, "Female": 1}
df.replace({"Gender": genders}, inplace=True)
df = pd.concat([df, pd.get_dummies(df["Geography"], prefix="Geography")], axis=1)
df.drop("Geography", axis=1, inplace=True)

We are now ready to train our model with the preprocessed dataset:

df.head()

4 1 43 2 125510.82 1 1 1 79084.10 0 0 0 1

Dataset preparation

For training our model, we will randomly split the dataset in 3 parts:

  • training split with 60% of the rows
  • validation split with 20% of the rows
  • test split with 20% of the rows

The test dataset will be our held out dataset for model evaluation.

train_df, test_df = train_test_split(df, test_size=0.20)

# This guarantees a 60/20/20 split
train_ds, val_ds = train_test_split(train_df, test_size=0.25)

# For training
x_train = train_ds.drop("Exited", axis=1)
y_train = train_ds.loc[:, "Exited"].astype(int)
x_val = val_ds.drop("Exited", axis=1)
y_val = val_ds.loc[:, "Exited"].astype(int)

# For testing
x_test = test_df.drop("Exited", axis=1)
y_test = test_df.loc[:, "Exited"].astype(int)

Model training

We will train a simple XGBoost model and set its eval_set to [(x_train, y_train), (x_val, y_val)] in order to collect validation datasets metrics on every round. The ValidMind library supports collecting any type of “in training” metrics so model developers can provide additional context to model validators if necessary.

model = xgb.XGBClassifier(early_stopping_rounds=10)
model.set_params(
    eval_metric=["error", "logloss", "auc"],
)

              max_leaves=None, min_child_weight=None, missing=nan,

predictions = [round(value) for value in y_pred]
accuracy = accuracy_score(y_val, predictions)

Running a model evaluation test plan

We will now run a basic model evaluation test plan that is compatible with the model we have trained. Since we have trained an XGBoost model with a sklearn-like API, we will use the SKLearnClassifier test plan. This test plan will collect model metadata and metrics, and run a variety of model evaluation tests, according to the modeling objective (binary classification for this example).

The following model metadata is collected:

  • Model framework and architecture (e.g. XGBoost, Random Forest, Logistic Regression, etc.)
  • Model task details (e.g. binary classification, regression, etc.)
  • Model hyperparameters (e.g. number of trees, max depth, etc.)

The model metrics that are collected depend on the model type, use case, etc. For example, for a binary classification model, the following metrics could be collected (again, depending on configuration):

  • AUC
  • Error rate
  • Logloss
  • Feature importance

Similarly, different model evaluation tests are run depending on the model type, use case, etc. For example, for a binary classification model, the following tests could be executed:

  • Simple training/test overfit test
  • Training/test performance degradation
  • Baseline test dataset performance test

Initialize VM model object and train/test datasets

In order to run our SKLearnClassifier test plan, we need to initialize ValidMind object instances for the trained model and the training and test datasets:

vm_model = vm.init_model(model)
vm_train_ds = vm.init_dataset(dataset=train_ds, type="generic", target_column="Exited")
vm_test_ds = vm.init_dataset(dataset=test_df, type="generic", target_column="Exited")
Pandas dataset detected. Initializing VM Dataset instance...
Inferring dataset types...
Pandas dataset detected. Initializing VM Dataset instance...
Inferring dataset types...

We can now run the SKLearnClassifier test plan:

model_plan = vm.run_test_plan("sklearn_classifier", model=vm_model, train_ds=vm_train_ds, test_ds=vm_test_ds)
